Betrayal and the Fight against German and Austrian Espionage on the Eastern Front of the First World War (1914— 1916)

The nature of the phenomenon of betrayal on the western borders of the Russian defense is studied. Some operational-search and administrative-legal measures of prevention and prevention of facts of treason and German espionage are considered. The authors believe that the practice of forced eviction of “hostile population groups” from the Vistula region has justified itself. The conclusion is made about insufficient study of archival documents on the history of counterintelligence ensuring the security of the Russian army in the western theater of military operations of the First World War.
